Apple Fuels iWatch Rumors by Seeking Exercise Physiologist to Lead Fitness Tests
Design and run user studies related to cardiovascular fitness & energy expenditure, including calories burned, metabolic rate, aerobic fitness level measurement/tracking and other key physiological measurements.
Candidate will be knowledgeable about the physiological effects being measured and how to avoid potential inaccuracy and experimental error due DOE flaws and/or reference monitor (i.e. metabolic cart, etc.) usage issues.
The role will need to apply relevant knowledge to the design of products and their testing/validation through user studies.
The requirements of this position suggest the employee will be working on Apple's rumored fitness-focused wearable. The company has been making a strong push into the medical and fitness field with recent hires like sleep expert Roy J.E.M Raymann from Philips Research and Michael O'Reilly, M.D., former Chief Medical Officer of pulse oximetry company Masimo.
This elite team of medical researchers is presumably designing Apple's iWatch along with fashion experts like Former Yves Saint Laurent CEO Paul Deneve, who was hired last year to work under Tim Cook on a "special project". Apple's fitness band may connect to the iPhone via Healthbook, a fitness app expected to be released alongside iOS 8.
Update: Apple has removed the job listing from its site.
